Hello all,
I've referred to posts here a lot over the last few months. Now it is time to tackle a big project (for me at least) and I want to make sure I do it right.
I would like to add a bathroom with shower in my basement. The floor is a 4" slab.
There is an existing drain (3" interior diameter/4" exterior - made of metal - would this be a steel pipe? It is original to the home - 1940's) that comes out of the floor about 1" before it is capped. Previously this drain continued up to the 1st floor where it met the kitchen sink and then vented out of the house. The kitchen sink no longer exists in that location so the drain was cut just above the basement floor and removed.
I have three questions...
1) Can I tie into this existing drain for a shower, sink, and toilet?
2) What order must I/should I go in? ie shower -> toilet -> sink -> existing drain?
3) What do I need in regards to ventilation? This bathroom is smack in the middle of the basement - the nearest exterior wall is about 15' away. Venting through the roof is not feasible due to the layout of the rooms above. I have no problem running a vent through the ceiling joists and out the side of the house - is that allowed?
Any help is greatly appreciated. I have limited plumbing experience but am looking to learn. I am very competent in most other household remodeling areas. I have broken up/replaced sections of concrete slab before so that part of the project at least I know I have a grasp on.
Thanks in advance for all the wonderful advice I know I am going to receive!
